Will this be necessary with osmesa VTK wheels?

[banesullivan]

This entire action will be unnecessary with the new OSMesa wheels. They will bundle OSMesa in them (there will also be "slim" variants that do not bundle though)

[banesullivan]

FWIW, this action is used by a handful of non-VTK graphics projects too

@banesullivan where did you get the updated DLL?

I'm guessing it needs some other DLL(s) that are not present. Have you tried using DependencyWalker on it? You can see how I've done it programatically for another repo here when I had to debug:

• https://github.com/openmeeg/openmeeg/blob/main/.github/workflows/build_and_test.yml#L482-L485
• https://github.com/openmeeg/openmeeg/blob/main/build_tools/install_dependency_walker.sh

I could do something similar here if it would help figure out why the new DLL isn't working.

I have a vague recollection that this dependency chain is one reason I didn't update the MESA OpenGL DLL using the release version on the MESA website.

For example this msys/pacman url suggests there are a bunch of other dependencies for 23.0.1 s. You'd probably need the whole chain if you used that or a similar version...

This just isn't worth our time... closing.

But on a brighter note, VTK will soon publish VTK wheels with OSMesa embedded for Windows. See https://gitlab.kitware.com/vtk/vtk/-/merge_requests/10095

FYI, with the new OSMesa wheels being published for linux already and soon for Windows, this action will no longer be needed for PyVista's tests and I will likely move to deprecate it or focus it entirely for the qt use case
